What component of the atom did Rutherford identify in his gold foil experiment?
Through his gold foil experiment, Rutherford identified the nucleus and believed it to be compact but containing the majority of the atom's mass, and the electron cloud. He figured this out based on the deflection of the alpha particles, which rarely hit the nucleus, but sometimes would hit it and deflect at high angles.

1. It is used because gold was known to be a very inert element. 2. The use of gold had nothing to do with its reactivity, any more than the experiment had any connection to… chemistry. Rutherford wanted to fire alpha particles through the foil. Alpha particles are not very penetrating; a sheet of notepaper will stop most of them. To achieve a reasonable percentage of penetration the foil needed to be really thin. Gold is highly malleable; gold leaf can be made in thicknesses around 100 nm or 4 micro-inch. It was the best material for the job.
How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
Rutherford expected the alpha particles to shoot right through the gold foil. At the time it was assumed that an atom was a mix of electrons and protons. When Rutherford s…hot the particles through the gold foil some of the particles reflected back, while most just shot right through. This indicated there was a small dense positively charged nucleus in the atom.
Because he bombarded the alpha rays on thin foil of gold and alpha rays can not pass through air or gases.
protons are located in the nucleus of an atom
1) Atoms were mostly empty space (because most alpha particles went straight through the gold foil) 2) Atoms had a dense nucleus (because few alpha particles bounced straight… back from the atoms) 3) The nucleus of atoms were positively charged (some alpha particles were deflected at large angles)
The conclusions were that the nucleus in an atom must:- (1) Be positive as it repelled the positive alpha-particles (2) Have a high mass, as the deflections were massive … (3) Be very small as only a few of the particles were deflected
In 1911, Ernest Rutherford conducted an experiment that proved that the mass of an atom is concentrated in the center (nucleus) of an atom. It also proved that an atom is most…ly empty space. In his experiment, he emitted positively-charged particles at a piece of gold foil. Many of the particles went straight through, some were deflected, and some were reflected.
The Geiger-Marsden experiment, which is also called the gold foil experiment or the Rutherford experiment, was conducted by Hans Geiger and Ernest Marsden in 1909, under Earne…st Rutherford's direction. You need a link to the Wikipedia post on this ground-breaking experiment, and we've got one for you.
Nucleus - Rutherford fired particles at gold foil, and most went straight through. This showed that most of atoms are empty, and that most of the mass only occupies a small pa…rt of the atom. This part is known as the nucleus.
Rutherford was a scientist who shot alpha particles through a very thin sheet of gold foil. The results of this experiment are the following: -Almost all alpha particles passe…d right through the Gold foil -A few alpha particlas were deflected and repelled .....These conclusions show that the majority of the atom of gold is empty space except for a small, positively charged nucleus. This nucleus is the reason why some alpha particlas were deflected(Alpha particles have a positive charge, which is repelled by a positive nucleus).
In the experiment, Rutherford found the nucleus using gold foil.
That atoms have a positively charged nucleus.
Yes , Rutherford's gold foil experiment was about the atomic structure. He bombarded 8000 alpha particles on the gold foil and the source of alpha particle was POLONIUM (an el…ement in periodic table). After bombarding rays, he observed that most of the rays passed without deflecting, and few rays deflected backward. By this , he concluded that most part of the atom is empty. That empty part is also called extra nuclear part or energy levels, shells or orbit . Nucleus lies in the centre of the atom which carries positive charge. It was his assumption which was right. Because two like charges always repel each other. since alpha particles carries positive charge and it can repeled by only positive charge. Electrons revolve in extra nuclear part.One thing that was wrong about Rutherford experiment was his assumption that eletron while revolving in the extra nuclear part continuously radiate energy.
It demonstrated that there is positively charged nucleus and the atom is mostly empty spaced.
Rutherford discovered that atoms are mostly empty space except for the nucleus at the center of the atom.
In Rutherfords gold-foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positvley charged center because?
When the beam of electrons passed through the gold foil, some were deflected at odd angles. This indicated the presence of a more massive portion of the atom that could be… explained by the raisin pudding model.
In Rutherfords gold foil experiment some of the aimed at gold atoms bounced back suggesting that a solid mass was at the center of the atom?
In Rutherford's gold foil experiment, some of the Alphaparticles aimed at gold atoms bounced back, suggesting that asolid mass was at the center of the atom. They suggested …that most of the mass of the atom is concentrated atthe center and the center is positively charged.
